JOHN OBRIEN, OF ST. LOUIS, MISSOURI.

COMBINED FLANGlNG-MACHINE AND DRlLL-PRES S.

SPECIFICATION forming part of Letters Patent No. 362,308, dated May 3, 1887'.

Application filed October 18, 1836. Serial No. 210,518. (No model.)

To all whom, it may concern:

Be it known that I, JOHNOBRIEN, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Combined Boiler-Flanging Machines and DrillPresses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side elevation of the device, showing it in position as a flaugingmachine. Fig. 2 is a detail perspective view of a boilerhead, showing a flanged flue-hole. a similar view before the hole is flanged. Fig. 3 is a similar view to Fig. 1, showing the device in position as a drill-press. Figs. 5 and 6 are vertical sections through the device that is used on the machine when applied as a-drillpress, the shaft being shown in side view. Fig. 7 is a vertical section through the chuck arrangement and former, and also the anvil or support of the fianging mechanism.

My invention relates to an improved ma chine intended for interchangeable use as a fiangingmachine or a drill-press, and which can be readily and quickly changed from one to the other; and my invention consists in features of novelty hereinafter full y described, and pointed out in the claims.

Referring to the drawings, A represents a frame supported by a suitable base, B, and

having extensions A, through which passes a vertical shaft, 0, journaled in boxes 0, by

which it is connected to the extensions A of connection with the cog-wheel D, is not interfered with.

When the device is in use as a flanging-machine, there is connected to the shaft 0 a lever, E, fulcrumed on a standard, E, extending upward from the frame A, the outer end of the lever terminating in a handle, E

As a means for connecting the shaft to the lever, I have shown aeollar, F, connected to Fig. 4 is.

the end of the lever by means of a link, F, which slips over theupper end of theshaft and is held thereon by a connecting-pin, F, the collar being connected to thelink F by abolt, F. On the lower end of theshaft is secured a chuck, G, which receives the non-circular end H of a hollow clutch-collar,- H, the teeth on the lower .end of the collar meshing into teeth on the upper end, I, of the collar 1, as shown in Fig. 7. The collar is screwthreaded, to receive a screw-threaded shaft or rod, J, which feeds the former downward as the shaft 0 is turned. The anvil or table L, on which rests the piece of metal M, being flanged, is made hollow, as 'shown in Fig. 7; but in this, per se, [claim no invention.

Surrounding the shaft 0, near the upper journal-box, O, is a sleeve, N. Surrounding this sleeve N, and having screw-threaded connection therewith, is a second sleeve, N, having an upper flange, N bolted to the upper extension, A, and the upper box, 0, and'the .lower end of this sleeveispreferablyprovided with a flange, N. 0n the lower end of the sleeve N is formed or secured a hand-wheel, N*, for turning said sleeve, whereby it is caused to move up or down, according to the direction in which it is turned, by reason of the engagement of the threads on its exteriorwith the threads on the interior of the fixed sleeve N.

N is a collar fitting loosely on the shank 0 below the hand-wheel and sleeve N, and provided with a binding-screw, N, and T a collar similarly fitted upon said shaft above the sleeve, and likewise provided with a bindingscrew, P, whose end is. adapted to enter a slight depression, 0 in the shaft 0. This collar is of such diameter that it may rise and fall freely within the hollow sleeve N when its binding-screw is screwed in, so as to clamp it to the shaft. When both of these collars are clamped to the shaft by their respective binding-screws, one above and one below the sleeve N, as shown in Figs. 3 and 6, it is manifest that there can be no relative longitudinal movement between the parts 0, N, N, and T, and that the shaft 0 or sleeve N may revolve freely independently of each other, the collars move the shaft longitudinally in its bearings,

N and T moving with the shaft; hence, to.

either upward or downward, it is simply necessary to turn the hand-wheel N in one or the other direction, as may be required to produce the desired result.

\Vhen the device is being used as a drill press, the collar and former H and I are removed, and a tool, 0, secured in the chuck G. The lever E is next discon nectcd from the shaft 0 by removing thepin F or thebolt 1?,(the latter is shown removed in Fig. 3.)and the shaft 0 is fed by the hand-wheel N.

It will now be seen that when the sleeve N is turned downward in the sleeve N by means of the hand-wheel N the drill will be fed down upon its work, the shaft 0 being prevented from slipping through the sleeve N as it is turned down by means of the collar N, and when the wheel is reversed and turned in the other direction the drillwillbc raised, owing to the shaft C being prevented from slipping or movingin the sleeveXby the collar T.

WVhen the device is used as a flanging-machine, there is no connection between the shaft 0 and either of the sleeves, thehand-whcel N, or the collar N but the shaft works freely through them, and operates as though those parts were not present.

It will thus be readily understood howrthc device can be quickly changed from a machine suitable for flanging boiler heads or other pieces of metal to a drill-press, and how, by simply turning outward on the screws I and N, the feed can be changed to make it suitable for a flanging-maehine.

I claim as my inventio'n- 1. Inacombinedflanging'machineanddrillpress, in combination with avertical shaft provided with means for the attachment of the former or feeder and mechanism by which it is rotated, the inner sleeve provided with a hand-wheel and surrounding the shaft, station ary outer sleeve having scrcwthreadcd connection with the inner sleeve, and collars located above and beneath the inner sleeve, substantially as and for the purpose set forth.

2. In a combined Hanging-machine and drillpress, a vertical shaft and mechanism for rotating it, in combination with an inner sleeve provided with a hand-wheel, a pair of collars located, respectively, above and below said sleeve, and having screws for securing them to the shaft, whereby the latter is held against longitudinal movement in either direction independentl y of the sleeve, and an outer stationary sleeve having screw-threaded connection with the inner sleeve, substantially as and for the purpose set forth.

In a combined flanging machine and drillpress, a vertical shaft and mechanism for rotating it, in combination with a lever removably connected to the shaft, a sleeve provided with a hand-wheel and surrounding the shaft, loose collars surrounding the shaftlocatcd, respectively, above and below the sleeve and havin g clam p-screws,and an outer stationarysleeve having screw-threaded connection with the inner sleeve, substantially as and for the purpose set forth.

4. In a combined Hanging-machineand drillpress, in combination with the vertical shaft and mechanism for rotating it, a. lever removably connected to the upper end of the shaft, a sleeve surrounding the shaft and provided with a handwheel, collars located above and beneath said sleeve and provided with setscrews for securing them to the shaft, and the outer stationary sleeve having screw-threaded connection with the inner sleeve, all arranged and operating substantially as and for the purpose set forth.
